[07:39:01] karsten_thomann joins the room [08:54:17] equinox joins the room [09:03:45] Michael Barnes joins the room [09:05:08] adrianfarrel joins the room [09:09:56] You-GT joins the room [09:11:12] I am not getting the audio, is everyone having this problem? [09:11:48] I can confirm, here also no audio [09:14:51] hm, i guess we have no scribe either [09:17:41] I'm not in the room [09:17:48] Did anyone raise a ticket on the audio? [09:17:58] Send to tickets@meeting.ietf.org [09:18:07] (for the audio) [09:18:08] i'm in the room but no idea if/what i can do [09:18:57] For jabber scribe you can kick the chairs! [09:19:03] Or do it yourself :-) [09:19:19] For audio, someone who knows where the meeting is should just raise the ticket [09:20:37] i've sent a mail to tickets@ [09:20:50] currently, acee is presenting extend-LSA [09:20:52] is there working video? [09:22:03] Cyril Margaria joins the room [09:22:54] I don't know as there is no meetecho or webex for this room... [09:23:11] grah, so you don't see the slides either i assume [09:23:23] we're at Next Steps for Draft on extend-LSA [09:23:30] Has someone the audio? [09:23:56] Cyril: audio stream is apparently broken, a ticket #683 is open for that [09:24:34] Thanks. [09:29:25] now: OSPFv3 auto-config draft [09:29:31] history [09:29:41] (on the Extend-LSA draft there were 2 questions:) [09:29:51] Cyril Margaria leaves the room [09:30:09] #1: adding some bits to define behaviour for routers that don't support a particular LSA/feature, etc. [09:30:17] (this was discussed on the ML a while back) [09:31:01] Acee mentioned that unlike BGP, we don't modify LSAs, and it doesn't make too much sense [09:31:42] #2: communicating migration in the Router LSA, the suggestion was to actually use 2 bits and communicate the configured compat mode [09:31:59] which was positively received [09:32:08] @equinox: Thanks for your updates [09:32:14] now OSPFv3 auto-config, slide "Ginsberg Elder Respect Issue" [09:35:44] audio just came on [09:35:46] We have audio :) [09:35:52] whoo. [09:35:54] praise be [09:36:05] also, now at slide "Changes since Berlin" [09:36:12] @equinox thanks for stepping in [09:37:09] question from audience (?), middle point on changes since berlin [09:37:26] on retaining the OSPF Router ID in nonvolatile, suggesting this should be MUST not SHOULD [09:37:54] (sorry, i have trouble picking up names of people) [09:38:16] @equinox: Is the questioner at the mic? He was barely audible. [09:38:22] he is, the mic is apparently off [09:39:28] another question, on where this draft can/cannot be used, because retaining the router ID in nonvolatile is always discussed under homenet context [09:39:58] Acee responding (paraphrased) "environments that can't tolerate this shouldn't use the draft" [09:40:13] (audience) "it's for homenet and really stupid service providers" [09:41:02] Fred Baker now at mic, suggesting it's "small networks" but should still be considered important [09:42:42] [09:43:02] @equinox could you perhaps turn on that mic? [09:43:13] Michael Barnes, Fred tried before he asked his question [09:43:25] he couldn't get it on [09:43:46] no further questions on autoconfig [09:43:47] now: now security extensions for OSPFv2 [09:43:55] (...with manual keying) [09:44:30] [Changes since -05] [09:45:10] [09:45:20] no questions - very short 10min ;) [09:45:29] Stewart Bryant joins the room [09:45:49] now: OSPF Two-part Metrics [09:46:02] [Summary] [09:46:47] [An example network] [09:47:38] [RFC 6845 Hybrid Interface] [09:48:10] equinox is now known as David Lamparter [09:48:18] [Observation 1] [09:49:16] [Observation 2] [09:49:52] [Proposed solution] [09:52:12] [Advantages] [09:53:21] [Encoding from network-cost, Option 1 - MT metric] [09:54:08] [Option 2 - stub link] [09:54:41] FWIW the NOC just reported the fix for the audio.. "Plugged cable in" [09:55:21] [Compatibility: Encoding Option 1] [09:55:35] heh. [09:57:28] [Compatibility: Encoding Option 2] [09:58:03] [Plan] - tending to option #2 [09:58:15] questions [09:58:27] none from audience apparently [09:58:51] Acee commenting, encoding might not need to be changed, just the SPF calc [09:59:12] but support for different metrics per direction is desired apparently [09:59:29] audience question: complexity? [10:00:22] (same speaker) functionally desirable, but unsure if it warrants the complexity [10:00:38] different speaker commenting: persistent loops from routers using different calc [10:01:34] also, question how it's handled wrt DR & BDR, speaker responding it's the original router and the DR/BDR pick up from that [10:02:06] on different calculation methods, the compatibility options would ensure the calculation methods are consistent through the network [10:02:50] (speaker) with option 2, RI LSA would be checked domain-wide [10:03:38] audience question: flapping last remaining old router [10:03:53] (network going back & forth) [10:05:59] question in which LSA the stub link would go, in particular looking at OSPFv2 vs. v3... [10:06:10] (guess that question was on the stream since it was from wg chair...) [10:06:23] no more questions [10:08:07] Cyril Margaria joins the room [10:08:39] searching for slides for next presentation... [10:09:41] there we go, OSPFv3 over IPv4 for IPv6 Transition [10:09:49] [Applicability] [10:11:06] [Transition to OSPFv3] [10:11:45] [OSPFv3 Packet in IPv4] [10:14:51] [Deployment] [10:15:42] questions [10:16:32] (Abhay Roy): link locals are cheap, so from that point it's not needed, but it solves the AF virtual link problem [10:16:49] who is at the mic? [10:16:54] (audience [?]) people want this, have run the numbers, cuts costs by 40% [10:18:03] Rand Atkinson (or somesuch) [10:18:10] thx [10:19:13] adding/deploying linklocals is apparently not permitted because some ASICs don't handle ipv6 headers :o [10:19:35] so for them, the over-ipv4 transport solves that problem [10:20:12] (Abhay) this should be added to draft [10:20:48] (Acee) maybe there are new features on OSPFv3 (and not v2) and this would be a way to use those [10:21:36] no more questions it seems [10:21:58] now: OSPF Routing with Cross-AF MPLS TE Tunnels [10:22:10] [Introduction] [10:25:21] [Problem definition] [10:26:04] (Acee) why no "cross-use" e.g. of tunnel signalled for IPv4 for IPv6 [10:27:40] [Problem definition (cont.)] [10:29:24] [Simple (but problematic) solution] [10:29:26] Cyril Margaria leaves the room [10:34:42] [Neccessary digression - RFC 5786] [10:35:37] [RFC 5786 - sub-TLV format] [10:36:07] [Proposed solution] [10:37:11] Alia Atlas joins the room [10:37:14] [Proposed solution (example)] [10:41:11] questions [10:42:01] audience: providing ipv6 reachability over a network that supports IPv4 and MPLS, and have LSPs cross from one IPv6 island to another... [10:43:05] ... that wouldn't work with ships in the night because it's islands, but with this it should when the islands are interconnected (?) [10:43:16] ((not sure if i got this right)) [10:44:04] (Acee) this would be an informational draft [10:45:59] (Anton) there's an interop problem that needs to be addressed [10:47:26] (Alvaro [?]) it's changing details on the addresses TLV, so that's standards [10:48:11] (Acee) needs more discussion, also 6827 changed the addresses TLV too [10:48:29] no more questions [10:48:36] now: Signaling Entropy Label Capability w/ OSPF [10:48:39] [Motivation] [10:49:48] [Advertising ELC using OSPF] [10:50:38] ... very short presentation. questions. [10:51:01] (audience) it's not the router that is ELC capable, it's the interface... [10:52:28] (Xiaohu) TLV indicates support on all interfaces [10:52:54] (audience) problematic, linecards to customer might not need it, but core network has it [10:53:19] no more questions apparently [10:53:48] now: OSPF Node Admin Tag [10:54:11] [Rationale] [10:55:32] [Per-Node Admin Tag TLV] [10:57:46] [Application Examples] [10:59:06] probably asking on list for WG adoption, questions [10:59:20] (audience) 3309 uses 32 bits, maybe align with that [11:00:40] (Acee) not having well-known values needs people to not hardcode values [11:01:49] ... multiple tag values, multiple instances of RI LSA [11:02:23] respin 4970, would allow using more than 64 tag values [11:03:00] last draft, WG seems done [11:03:12] Stewart Bryant leaves the room [11:03:13] TTZ draft will be presented again in toronto [11:03:24] audience calling for participation in netmod OSPF stuff [11:06:43] Thanks for scribing David [11:06:58] Michael Barnes leaves the room [11:07:03] yes, appreciated [11:07:40] You-GT leaves the room [11:12:19] Alia Atlas leaves the room [11:22:38] Very many thanks to David.
